这里举了一夫一妻的例子。
实体：
package uni.one2one;
public class Husband {
private int id;
private String name;
private Wife wife;
public Husband() {
}
public Husband(int id, String name, Wife wife) {
super();
this.id = id;
this.name = name;
this.wife = wife;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Wife getWife() {
return wife;
}
public void setWife(Wife wife) {
this.wife = wife;
}
}
package uni.one2one;
public class Wife {
private int id;
private String name;
public Wife() {
}
public Wife(int id, String name) {
super();
this.id = id;
this.name = name;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
hbm配置文件：
<hibernate-mapping>
<class name="uni.one2one.Husband">
<id name="id" column="did">
<generator class="native" />
</id>
<property name="name" type="string" column="name"></property>
<many-to-one name="wife" unique="true"></many-to-one>
</class>
</hibernate-mapping>
<hibernate-mapping>
<class name="uni.one2one.Wife">
<id name="id" column="did">
<generator class="native" />
</id>
<property name="name" type="string" column="name"></property>
</class>
</hibernate-mapping>
测试文件：
public class Test {
@org.junit.Test
public void testAdd() {
SessionFactory sf = HibernateUtil.getSessionFactory();
Session session = sf.getCurrentSession();
session.beginTransaction();
Wife wife = new Wife();
wife.setName("wife");
Husband husband = new Husband();
husband.setName("husband");
husband.setWife(wife);
session.save(wife);
session.save(husband);
session.beginTransaction().commit();
}
}
测试结果：
Hibernate: insert into Wife (name) values (?)
Hibernate: insert into Husband (name, wife) values (?, ?)
